Course Syllabus
Keep in mind the following
•
•
This is a graduate level class-you will be expected to
pursue topics on your own.
Use the web and other references in addition to text
•
•
and notes.
This is a new area-leading edge-course is still evolving.
Instructor is only a facilitator, the course is a team effort.

Overview - 2


Current Manufacturing practice is not
sustainable.
The motivation to change is
» compelling
and
» urgent

but the answers are not yet known.

Consumption of fossil fuels
Environmental damage
Extermination of species
Loss of vegetation
Contamination of groundwater, lakes

Motivation (why urgent)
Rate of fossil fuel depletion
 Environmental and health hazards due
to

» Toxic wastes
» Radioactive wastes
» Acid rain
» Landfill problems

Pollution - 1

CO2 rise
Since 1750,
carbon dioxide in
the air has risen
by more than
30%, due to
human activities.
It could double
by the year
2065.

Pollution - 2
CH4
rise
Each molecule of
methane traps
heat 20 times
more effectively
than a carbon
dioxide molecule.

Pollution - 3
This chart shows how much
warming could be caused
by each of the gases that
human activities release.
Carbon dioxide accounts
for three fourths of the
predicted increase in the
greenhouse effect.

Getting from here to there:
»
»

Reduce energy / goods / services
Change the way we satisfy our needs
Option #2!

Industrial Ecology - 1

Need to move towards “sustainability”
»
Industrial Ecology:
–
The means by which humanity can deliberately and
rationally approach and maintain a desirable carrying
capacity, given continued economic, cultural, and
technological evolution.

Industrial Ecology - 2

Systems view:
»
The concept requires that an industrial system be
viewed not in isolation from it’s surrounding
systems, but in concert with them. It is a systems
view in which one seeks to optimize the total
materials cycle from virgin material, to component,
to product, to obsolete product, and to ultimate
disposal.
